Team Goliath™ heads further into the cave tunnel. Big Un is keeping his thoughts to himself, and keeping a bit of distance from Mark, in case he goes off again, but can't recall anything as uncontrolled as the tendrils of energy that hurt his friends before. Mark doesn't see anything out of the ordinary, provided that softly glowing blue-green mushrooms would be considered ordinary. They start cropping up along the walls and floor as you approach the tunnel opening out into a bigger space, and see a small field of mushrooms surrounding a quiet pool, the whole of it lit by glowing fungus, and a soft dripping from stalactites above sending ripples through the pool.

Talon plays a bit as the others take a breather. Ember tries shuffling some cards and almost loses a few, but amuses herself as she takes it easy. One of the cards gets away from her, slipping down towards where Blue is resting, and he instinctively gestures and speaks a word in a whistling, breathy language and it is caught by a gust of wind and carried back up to her.

Son spends some time poring over the book, and realizes that it actually makes a fair bit of sense! ((As a confirmed wizard, I'm going to do things a bit differently for you, since the book kind of gives you what all of your spells are, and everyone else still has to 'work for' theirs. As part of a short or long rest, I'll say you can make an Arcana roll like you did, and spend time studying one of the spells in the book, declaring what sort of spell you're trying to study (eg, an attack spell, a enchantment spell, etc.). At a DC 20, you'll get the spell that best fits your criteria and an additional spell. At DC 15, you'll get the one that best fits, at 10, you'll get something else, and below 10 you'll have stumped yourself. You'll still be able to potentially 'unlock' spells as normal via Memory Dice.) 

((Great! Anything for that 16+? He is looking for a utility spell. Or do you want a school?))

((Either school or description function would be fine!))

Son spends the rest studying an interesting spell in the book, after flipping around a bit. He knows the spell skywrite, and while it isn't prepared for today, he is certain he could cast it by following the instructions in the book, though it would take longer.

((You can use ritual casting, and have regained a Memory Die.))

"Huh. Well I understand this stuff! I guess I can write things in the sky. For some reason? Ten words. Anyone have something they want written in the sky? Not now, tomorrow?"

Son thinks hard on the spells, trying to trigger a related memory...

Memory die: 8

((What heck, might as well try! Better to know what you got before you need it.))

Quote from Rodgeir >>

"Huh. Well I understand this stuff! I guess I can write things in the sky. For some reason? Ten words. Anyone have something they want written in the sky? Not now, tomorrow?"

 "I can think of a few profanities I'd like to put up there. Bacaw!"

 Mark will proceed into the open space, looking around to see if there are any other entrances/exits. He'll also check out the water to see if it looks safe to drink. 

Survival: 5 

Talon remarks that he could think of a few things to put up there, and it occurs to Son that if it were a spell he had prepared, it would be a very convenient way of signaling to the bird man from the ground if he was above and ahead scouting. Son feels like skywrite resonated with another unclear ghost of a memory... he flips through the book, and lands on another spell, rapidly reading through it... AHA! comprehend languages!

Also not prepared, but one he feels that he could cast if he just took a few minutes time to follow the instructions in the book. 

Mark isn't sure, the water is dark and smells a bit eggy. The mushrooms suffuse the area with a soft fungal scent, that grows stronger as he steps through them, the spots were his feet crushing them glowing more brightly.

 ((Were there any other exits to this cave?))

((Just the way you came in. If this was the trail to Father's "Pool of Not Forgetting Stuff", this must be it, but it would seem that being in the habit of not forgetting stuff, and not having too many other visitors, he didn't bother to put up a sign.))

Big'Un will try to re-call if he has seen anything like those strange mushrooms before

nature (no mod): 13

They don't look familiar.

Mark heads back out to the group, taking a couple of the mushrooms with him.

"I think this is the place - there's definitely a pool in there, and it doesn't look quite like normal water.  Then again, these don't seem like normal mushrooms either, and to be honest, nothing around here seems normal.  This does seem like the only way in though, so it's probably pretty defensible if we decide to try drinking from it and camp here until morning."

"Heh. Remember I only have 10 words so it will need to be as colorful as possible."

Son is pleased that so many spells are coming back to him now and closes the book and puts it somewhere safe on his person as Mark comes out.

He gives the glowing mushrooms a look to see if they help him recall anything.

Nature:8

Then says,

"Well, I don't think we are in any shape to try and make it down the mountain and back to Father's today. I can also put an alarm spell on the entrance of the cave, which should be helpful?"

((What time is it? I am picturing late afternoon?))

((Pretty much.))

"Anyone got any food if we are staying here? Please not grubs. Or glowing mushrooms."

He stands to go check out the water himself.

"Talon, Ember, you want to come with me to see this pool of memory water?"

He examines the area around the pool then the pool itself for a magical feel. Maybe the magic is from the mushrooms? Maybe the stalactites in the ceiling? Maybe something in the pool?

Arcana:16

Perception (with modifier) as he looks in the pool and at the stalactites:6

"What's wrong with grubs?", Talons says, while considering the invitation. "I suppose I'll have to go in eventually..."

Does he recognise the mushrooms? 

Nature d20: 9

At the pool he'll taste the water. A little bit.

Investigation d20: 11

"Nothing wrong with them. Just had a lot of them today. Variety is spice of life."

He watches Talon drink,

"How's that taste?"

He stands ready to offer whatever assistance he can should Talon look like he needs it.

Med: 18

Mark heads back in and kneels in front of the pool.  He stares into the water, contemplating it, and all that has happened.  He tries to think of what could have led him to this place, and what his role is.  He feels like he should be protecting those he's with, and feels he isn't doing a very good job at that.  If only he knew more about who he was or why he was there....

Memory: 1

Blue will try to identify the mushrooms as well.
