This mod adds two new major structures to the deep dark biome, plus a few small ones. These structures have unique modded loot which can be used to craft a new sword.
Alpha Version:
Added the altar, citadel, meteorite and miscellaneous platform structures
Added loot tables for chests in the altar, citadel, platforms, and minor modifications made to ancient city loot tables
Added 6 new advancements
New blocks: Meteorite Block, Darklight Core, Extinguished Darklight Core, Nebulous Sculk, Starsilver Ore New tools: Skybreaker (sword), Soulbinder (hoe)
New items: Starsilver Shard, Starsilver Fragment, Spirit Fragment, Blade Fragments - Upper, Middle, Lower, Stardust Signet
TL;DR, a small deep dark expansion for people tired of going into the biome and not finding anything. There's a lot more in the works for the beta version, but for now, it's just a minor addition.
