Kat wasn't sure if she was making good time or not. The scenery was rather samey and when that is added together with the continual increase in the viscosity of the sludge she had to walk through… well it just made things very hard to put into perspective. It was only just recently Kat felt she'd passed 'the centre' or as close as they were going to get. She could feel the muck getting easier to run through with every step. Or that's what Kat was telling herself anyway.
She was using her tail and wings a lot more then she'd imaged as well. They helped in a surprisingly large number of ways when she was running through what couldn't really be called 'water' unless you were really stretching it. Her wings and tail both provided a good deal of balance, and her tail was able to slap against the poison to give her a further boost with every step, while her wings helped mitigate some of the weight she was carrying and sink a bit less.
