In Spiral Knights, someone just bailed out of my party because he couldn't "make it to vana". I also heard someone in the arcade say "guess we're back to vana running for today".
Chances are, they're referring to Lord Vanaduke, who is a boss down in the Firestorm Citadel down in tier 3.
The party member who bailed probably didn't want to spend his energy without making to a boss.
The others were probably lamenting that they had to work their way to vana instead of being able to catch a ride with a party that was almost there already.
