Knights of the Round Table

This mod adds takes inspiration from Arthurian legend and series like seven deadly sins and the fate series. It adds in 1 new ore, 8 new weapons, 2 dimensions, 3 biomes and 7 factions into your world. Seven of the eight weapons give you a different power.

The factions are Demon, Angel, Fairy, Giant, Wizard, Vampire and Merfolk each with four variants. Each faction can be tamed. Use dragon flower for fairies, faerie fruit for angels, sea pickles for merfolk, books for wizards, beef raw or cooked for giants, and veils of blood for vampires and demons. Demons are also hostile to player before taming.

The new dimensions are heaven and the underworld. Make the portals with gold blocks and polished Blackstone respectively, and craft their respective igniter.  

Goibniu ore can be used to craft 7 of the weapons. Surround the ingot in the dropped item of one of the factions to obtain blessed iron and use the desired blessed iron to craft your desired weapon. Excalibur can only be obtained in creative or by trading with a weaponsmith. Excalibur is the only weapon that doesn't have a power at the moment.  

Note the skins of the factions mobs were not made by me, only the giants were.
