There are no other signs of traps, or tracks, in this room.

What does the map look like so far? I wasn't limiting the search to that room, Tempe will move further in, if there is a way. 

After the 20 by 20 entry room the far doors open into a vast chamber that stretches beyond the limits of your vision. It is 80 feet wide, 40 feet to each side of the doors. After that it stretches off into darkness. Along each side of this vast chamber is a row of archways spaced about 10 feet apart.

Pepin will send dancing lights into the vast chamber to get a better view of things

Now that you can see more it does look even grander as the ceilings are 30 feet high, and the chamber stretches even further the more of it you can see with those same arches on each side spaced about 10 feet apart.

"I suppose that works as well, Pepin, I can see well enough for Sixty feet in the dark, to make things out, but I should of learnt that spell." Tempe, 'slightly shrugs' in envy.   "I know some that can make it look, 'human', can you?" 

Tempe says as he sends Slip to investigate the archways.

So far you can see 12 archways, 6 on each side, and as you move further into the chamber more archways are revealed.

Which one does Slip investigate first?

First one on the Left1thru3 or the Right 4thru6 =3 within 100ft

 Slip flies to the closest archway, on the right, to check it out.

It proceeds down several dozen feet and ends in a crypt with a single sarcophagus.

Randall:

”Hmm,” says Randall, “This area seems to be a mausoleum of sorts.  Let us be on the lookout for undead, since an unguarded crypt can often be corrupted for such purposes.”

Randall evaluates the region for signs of undead activity:  Passive Perception 20, Religion:  19

Tempe looks upon the coffin with Slip, "This does seem to be a 'Crypt, we should proceed with caution.'" Tempe looks for ruins or writings. Perception 19 

Pepin looks at the sarcophagus for any religious signs he might know

Religion: 18

Randall and Tempe notice some runes etched into the stone sarcophagi and Valanthe translates, "Final resting place of the elven hero Aloro."

Randall:

Randall checks to see if the crypt has remained undisturbed, trying also to recall if he has read about this Elven hero.

Perception:  26

History:  17

The crypt is undisturbed and you've heard the name Aloro a few times, mostly younger elves and you now surmise that perhaps they were named after this hero. None of the 'Aloros' you remember were known as heroes. And this crypt does look to have survived for centuries.

Randall:

”It appears to be undisturbed,” says Randall, “Let us move on.”

"It, would seem so Randal, perhaps magic shrouds it, let me ritual cast detect magic again" once ready, he checks the crypt and surrounding area, for illusions, or any other magic, "Valanthe, I wonder who this Aloro, was? Stories passed down from generation, too generation, sometimes, the names change to the more, 'likely', or more, popular ones. Is there a story that resembles, Aloro's? "

"No, sorry but it doesn't ring a bell. I've heard of some elves who go by that name but none were great 'heroes.'"

Randall:

Once the others have completed their investigations, Randall says, "Let's continue on.  We can look in on each crypt to be sure it isn't disturbed--I worry that a corruption here could foretell an undead menace."
