Vanilla MW only has cave-to-daedric-ruin transition pieces for the lavacave set. Since there's probably not a very compelling reason for this limitation (and TR has generally cobbled around the problem anyway), we might as well have connectors for the other cave types.
These are just edits to the vanilla in_dae_connect_lcave mesh to change the cavewall texture, haven't touched anything else.
A farmer in the Thirr River Valley area has a prize guar able to dance, do tricks, and even the limited ability to speak. This guar is the talk of the region and has even won the attention of dunmer nobility. Naturally the farmer's first thought was to breed the guar and sell its offspring for a massive profit. Unfortunately the day after mentioning this, the guar disappeared. "Bandits!" he thought, "They've stolen my prize guar! I see it's footprints going to the southwest!" At this point the player arrives and the farmer explains the predicament.
Similar to the Pilgrimage of the Seven Graces, TR has currently six pilgrimages, with plenty of room to expand from there. Pilgrimages are primarily used both in vanilla MW and in TR to give players an excuse to wander through beautifully crafted exteriors they otherwise wouldn't have a reason to. While this is an admirable goal in itself, it also helps if the trials are a bit more involved than "bring x to shrine get buff quest complete".
