What does cycling the spaceship's airlock have to do with a now-extinct Peruvian rodent?
In some virtual forums going AFK is the equivalent of passing out drunk on the couch at a fraternity party. Everyone from hackers to everyday participants will take shots at you, and you can expect your avatar to look very different when you get back. Hopefully you will notice quickly.
Draw the party together as debtors to the local lord, king, head of the thieves guild, or mercenary clan, who is forcing them to work together to pay off their debts.

It has been said that within the mountains (or was it the darklands?) there dwells a fluffy creature of immense cuteness.

The fact known by Jayel is that she killed a man with her bare hands, and has never looked back.
