Description
Sounds like the old Black Blood pipes in the Ringing Deeps are thawing out, but we haven't figured out a solution for all the goo they're packed with just yet. A few more budgetary meetings, though, and we're on it.
In the meantime, we earmarked a little cash for some temp help. That's you.
Get out there and refreeze those pipes.
