What do we know about limebloods?

Lime bloods were the blood caste between yellow and olive but they were all wiped out. Apparently they had powers that threatened the highbloods more than any other low blood caste so they were all hunted to extinction. Them being extremely good moirails is fanon. According to Calliope they had strange names. Calliope got all her information on troll stuff from Rose’s tome so this means she didn’t just make up lime bloods.
