Kaidan wants to go down there. So hopefully the air down there will be judged safe enough for entry. The mods have confirmed that Kaidan's omni-tool will be super-effective against any tech-related traps they may find down there. Kaidan can also use his biotics to fight off any resistance they may find. Would love to have some magic support for any magic-related traps, and other people who want to go down as an infiltration/possible distraction/extraction team? Who knows, I'm open to suggestions on what they can do once they're down there.

IDK if people want to split into teams as there are several different entrances or just choose one entrance. Either way, Kaidan is being offered as a fighter/support/tech-trap finder. It's been hinted by the mods that they use an entrance other than the one leading from HQ to the fountain as that one is in use.
