They also appear in the 3e MM2

The benefit of the 3e version is that it gives the 6 ability stats to go with the race to work as a base. For 5e, I've essentially given it a permanent quicken for all of their spells enabling them to cast a cantrip in addition to any other spell. From the War Caster feat, I took the ability to cast a single target spell instead of making an opportunity attack. I feel this fits it into 5e nicely, although it might be interesting to keep the spellweaving ability from earlier editions and allow it to cast a total of 6 spell slot levels, for instance: 4 1st level spells, and 1 2nd level spell. The Chromatic Disk ability is folded into its sorcery point values, allowing it to convert them in the same manner as a sorcerer.
