(OOC: Just so everyone is on the same page in our little mental journey, here is what the INITIAL phase of the shoring up the tunnel is going to look like when complete (minus train tracks and electrical lights).
While we do have further plans for the walls (and are open to other suggestions!) at this point we ONLY want to shore the tunnel up to make sure the ceiling does not cave down on anyone's head. We also will only be doing this for about 30 feet -- about what we estimate the damaged area is and a little beyond. We welcome anyone's help, as we intend this to include as many people as possible, even if it is located in the rogue tunnels.
Things you can do to help:
Moral support
Food and drink
Supply gathering
Go'fers
Anything else that you think might help or be fun!
I hope this clears things up a bit. We'll be updating as things progress. We do not anticipate this taking as long as the gates, but the gods are fickle creatures, and Balthy is a jerk. Stay tuned!)
