Wondering what this means and what I do about it

Hello! I'm not sure this is the fault of the LOTR mod, but either way, I could really use some help, or at least tell me what this gibberish means. Its a bunch of mods, ofc, and they all seem to be compatible, but it crashes while loading. The crash report is as follows: <hr> Minecraft Crash Report ---- // Surprise! Haha. Well, this is awkward.
