Ahead lies...?

[Nephrite]

'Are they hidden?'

[Anastasia]

Be more specific? I think I get what you mean, but I want to be sure.

[Nephrite]

No problem.

'Are the valuable items or knowledge hidden?'

[Anastasia]

"Yes."

10.

[Nephrite]

'Can they be found above us?'

[Anastasia]

"Yes."

11.

[Nephrite]

'Can they also he found below us in this tower?'

[Anastasia]

"Yes."

12.

[Nephrite]

'Is the power to be taken in the heartscale more effective on a dragon?'

[Anastasia]

"Yes."

13.

[Nephrite]

'Thank you.' Moore says as he ends the spell.

To the others, he speaks up, "We can find the answer we seek here in the tower, as well as how to save those trapped here. Be on the look out for hidden areas, as what we seek as well as other treasures hidden here."

[Anastasia]

"We have time," Xandra agrees, "Let us search carefully."

Okay, gimme MO for searching and any relevant checks like Perception.

[Nephrite]

Take 10 for 122 on Perception.

Looking primarily for hidden things that lead to notes, diaries or other valuables.

Any art or otherwise like that goes in the portable hole.

Still on the lookout for magical anything..

[Anastasia]

Going further down first, you find something - a sealed, hidden door in a basement. It radiates magic, hidden but easily defeated by your powerful spells. It's the same stone as the wall, set into it.

[Nephrite]

If needed we can have Jetina toss some dispels at it, alternatively I can antimagic Ray it.

Assuming the magic is sealing it and it isn't just a magic door for no reason...
