I don't have much time right now, so I'll keep it quick.
I've updated my Terrarian Dreamkeepers mod to tModLoader. You can get it here, or just download it through tModLoader which can be found here. You will need tModLoader anyway to play this mod.
I'm going on a holiday tomorrow, and won't be back for a week. If you find any bugs, please let me know. I'll fix them as soon as I can.

Edit: I hope it's OK to submit this to the Dreamkeepers-Fans featured gallery. I wasn't sure where else to put this.
