As D pondered the locations of these burial mounds Devin looked over at Eigeron.  "Oracle, how can we release Eigeron so he may find rest?" he asks.

"Given Harshnag's reaction following events at the entrance, and your own ties, Shaman Mullo, do either of you know of any of these mounds or where they may be located? And... how we may set about retrieving at least one of these relics?" D.O.R.K. asks

Mullo simply nods however Harshnag is sightly more fulsome in his response  "aye lass I know where they are. If you give me time I could even draw a map!"

 "Oracle, how can we release Eigeron so he may find rest?" Devin asks. In response the voices thunders out “ONLY BY KILLING HIS FATHER BLAGOTHKUS WILL HIS SPIRIT FIND REST!” as the voice dies away the Stone giant statue goes dark.

As Harshnag ponders and draws, Ilezenya tries to recall whatever he has learned in his wandering about these barbarian and giant temples. History: 19

Illezenya does not recall ever hearing any legends about the Uthgardt altars/ burial mounds

"Hmm, perhaps two questions left?  How about; Oracle, what is IYMRITH trying to do?"

"Oracle, what is IYMRITH trying to do?" Devin asks. In response, the voice thunders out "LIKE ALL OF HER RACE SOW DISSENSION AND CREATE MISCHIEF!" As the voice dies away the light on the Hill Giant dims away to nothing

"That is most assuring. It will perhaps need to be transcribed, as -- no offense, Warrior Harshnag, but I doubt you can create one small one enough for us to carry. Which I am prepared to do once we leave the chamber." D.O.R.K replied to the giant following the question of Eigeron's spirit. Though with that out of the way, she could once more gave her full and undivided attention to the questioning at hand, taking what mental notes were necessary along the way. "Hmn... Concerning. Such motivations may make them unpredictable. A weakness to exploit perhaps in the coming days." She comments on during another pause.

"RIght. Find Giant artifacts below barbarian temples. Kill Blagothkus to release this poor gian't spirit. Stop the giant chaos, and save the world. So, what are we going to do next week?" Ilezenya laughs at his joke.

Harshnag looks up from his map and grins "I reckon that's at least two weeks worth of work!"

Devin ponders for a few moments trying to determine what the last question would be, for he was sure there would be only one more.  He looked over at the spirit of Eigeron and made his decision.  "Oracle, where may we find Eigeron's father Blagothukus?"

"Oracle, where may we find Eigeron's father Blagothukus?" Devin asks "HIS SHADOW FALLS ON PARNAST!" As the words die away the light from the last giant statue - the Frost Giant - dims to nothing plunging the room into darkness.

I'm back! Had an exceptionally busy weekend and beginning of the week.

DM:

"Perhaps, Warrior Harshnag." D.O.R.K commented, but refrained from elaborating on her point. Once darkness falls upon the room the construct immediately fishing around in her pack for torches and a tender box. A task easier said than done in the dark, but one she intended to remain diligent in completing should Devin or the rest not prove quicker on the draw with their own light source once more. Regardless, once there is light again she addresses the group again, "It would be best we depart this chamber, examine Harshnag's map, and begin plotting our course for the most optimal advancement of our calling."

She then looks up to spirit of Eigiron, and in her best apologetic sounding tone adds, "It may be some time before we can free you depending on the course. But rest assured that should the gods will it, we will see you free." She assures, then canted her head to the side. "Inquiry: What do you know Parnast however?"

As the lights went out Devin Instinctively casts light on his shield. 

"Let's get out of here and back to the main portion of the temple." He says motioning to the portal.

He'll light the way for the others until all have exited and then follow them out.

After getting out 

"Harshnag, can you draw that map? Then we'll decide where to go. "

The party makes their way back to the temple where Harshnag completes the map.

Hey, we can see that one! :)

Mullo is still scowling as she leads (now on foot) Haetone back through the portal. Desecrating burial mounds. That is not idea she would ever have even thought possible before this day. Is it possible? What would Uthgar and his father think?

When the map is produced, and she looks at the landmarks — each Uthgar burial mound identified — her scowl deepens. The dishonor ... She begins to shake her head, taking a few steps back. "I ... This ... " She can't take her eyes off of the giant map as her head keeps shaking back and forth.

D.O.R.K had immediately set about producing parchment and charcoal to start the process of making at least a rough copy of Harshnag's map. Or at the very least, the bare basics of direction to a few of the notable locations. Yet for all of her determination to prepare things for the future, Mollo's reaction isn't wholly lost to her, as the note of conflict rung loudly in her auditory sensors.

"I...Perhaps there are rituals or rites that might allow for removal of what we seek with some discretion?" She asked awkwardly but suggestively to the Shaman. Though if that did not seem to work, she bow her head in thought, then look over almost pleadingly at Ebonitus and Devin.

Devin looks over the map.  "It seems the easiest would be the Great Worm Cavern, it is closest.  We have already killed their chief and their shaman.  If we take evidence of their defeat we can visit their mound and retrieve what we need.  All of these other places would take journeys of many days filled with dangers as we have already seen.   If we had better means of transportation I would suggest Silverymoon and Everlund.  We still have the platinum badge bearing the Triboar insignia of three boars charging forward. Darathra told us to bring it to one Dral Thelev at Danivarr’s House in Everlund. He will know what to do with it.  That may be an ally in this quest.  Additionally Harthos Zymorven had a greatsword we may be interested in.  He was at Zymorven Hall which, if I recall correctly, was on the north side of the Evermoors.  But those are journeys that would be at least a couple hundred miles there and then a couple hundred back."

Devin notices the discomfort of D and the concern that Mullo may have regarding the burial mounds.

"Last night I had a dream, sent by Mystra herself.  I was watching two people standing fairly close and facing each other. The image then pans out and I could see that they are in some sort of open space. The image then pans out and I could  see that the open space is a village square surrounded by a bustling market. The image then pans out again and I could see that there are wagons trains approaching the gates of what appears to be a large town. The image then pans out again and I could see that the town is on an island and that ships are approaching the island from various directions. The image then pans out again and I could see that the island is surrounded by several other islands. The image then pans out again and I could  see that islands are surrounded by ocean. The image then pans out again and I could see that the ocean is on a planet. The image then pans out again and I could see that planet is surrounded by several other planets all circling a large bluish star. About this time I heard the voice of my goddess “the small details are important but never lose sight of the bigger picture. What you see in the smaller picture may not reflect the bigger picture!”"

He looks over at the rest, but especially Mullo,

"I did not fully understand the dream.  I still don't but it makes more sense to me now.  This place I dreamt is the place the conch will take us.  We must keep the big picture of what we are trying to solve in mind, the small details, such a one of the burial mounds is important, but we cannot lose sight of the bigger picture.  This is what we must do.  We have no other way to reach this island, wherever it may be."

Mullo looks at Devin. She looks first angry and then worried. "And if someone had suggested stealing a holy relic from your holiest place?" She closes her eyes and shakes her head again. "Oh, Father, what would you have me do?" She turns and moves toward a wall. Sitting down, she removes her special bones and looks at them deeply (but does not cast augury).

Ebonitus has remained vigilant throughout this time. 

After some time thinking about it and reconciling the idea with himself, he says to Mullo and the others: "These relics were stolen from the giants. It is not so much that we would be desecrating the burial mounds and the resting places, so much as returning the relics to their rightful places and restoring the balance. If we can do this whilst respecting the burial mounds and the spirits within, it would be better for all. If we do not follow this path, ..." his voice trails off. He then observes the others, especially Mullo for a reaction.
