"Suzie does not need weapons, this one is a weapon, but C-O and some other squad-members are unarmed or underarmed."

She, and everyone else

There does not appear to be any conventional clothing, but one of the boxes seem to have spare guard uniforms. No helmets or ids though, so they'll work as clothes but not as a disguise.

Atsrea finds her armor and weapons easily enough, though not on display but in a box labeled "rare minerals."

In addition to the armor and weapons, which seem to have just very slight knicks to them(nothing that would hamper their structural integrity, just... someone removed samples of the material,) there is a Carolingian, or biking, a sword made of some black metal... Though since the blade has been cleanly snapped in half how useful it'll be is a matter for debate, as well as what looks like a gold bar... Wait a minute?

That's Adamantine.

"Wendigo hearts?" Roma says while holding a human heart in a jar in her clawed paw. "A those the things that happen when Canadians eat each other? Why would anyone want to...?"

In the display cases are some bronze spears of Egyptian make, though they ar clearly ancient and unusable. There is also very, very shiny looking gun with a note claiming it to be of Celestial Make... But that they have no idea how it works or how to turn it on, other than the fact that it seems like it's alive.

Charlotte holds up a vial of something green and gaseous she found in a box, and then pockets it without a word.

Suzie explores the room itself for a bit, taking things in, before gravitating to the stone tablet.

"Ye, as Amun-Ra journeys through the Underworld each night to ensure the rebirth of the sun upon each morning, so too shall our clan suffer no permanent defeat. Though our time of rulership is at end and we retreat into the shadow as our immortal Pharoah traveres the world to learn it's secrets, the children of Akkaba shall flourish again for as long as The First One, He Who Never Dies, shall live. May we pove our strength over all others. May we be fittest. Praise The First One, the Holy Revelation, his Riders of the Dark, and praise his prophets who ride out in his name to bring War, Famine, Pestilence, and Death to purge the Unworthy and test the fittest so that they may become the strong."

"...so, we've been kidnapped by an Apocalypse Cult?"
