[IC] Chapter 1-4: Cellars of Hate

[DM Surranó]

Sermour's isn't hacked; it's simply not sealed so tight and four of the six pitons (maybe better word than "bolts") are missing.
And the last one (Sirrith's) looks untouched (same as the first six)

Maul took it for granted that all bones in a single sarcophagus belong to a single person but upon (*ahem*) the armorer's (*ahem*) suggestion he looks again to verify and as much as he can confirm the bones were undisturbed until the party started raiding them.
