they are siblings, wormwood the eldest. not long after the god's disappearance and shortly before the formation of the council, wormwood rounded up up arariel and a number of other angels to convince them to overthrow the newly formed council and establish a new authority in heaven, led by wormwood. arariel and the others, disillusioned by the council and believing that god had died, went along with her. initially, their plan was successful, owing to wormwood's great strength, strategy, and cunning, which rivaled that of much of the council and some of the archangels despite her lower status. eventually and inevitably, she was defeated and executed when the remains of the council captured arariel and used him as leverage. none of the other angels of the brief insurrection survived besides arariel, who upon wormwood's orders descended down to the barren earth and lived in hiding for a long time, still fearing the wrath of the council. eventually, out of curiosity, arariel went into hell, which welcomed him with more or less open arms. since then, he has lived in wrath, hidden by gabriel and other lesser angels by what appears to him to be sheer coincidence but is really due to hell's illusions. arariel finds wrath to be comforting, as it reminds him of his old position as an angel of the waters of the earth before all the oceans on the earth dried up due to the great war.
other notes: arariel is about 5'8, wormwood is about 6'6. wormwood's machetes were forged in secret by another angel prior to the insurrection, and arariel's trident was originally used for water manipulating purposes but has become a weapon. arariel uses he/she pronouns and wormwood uses she/her (in defiance of god^_^)
