The idea is interesting, but reading the wiki, don´t know, sounds too much like cristianity, the idea of heaven and hell and the creation story (god created everything and then created a man and a woman? too biblical)
Besides, with the idea of god drinking blood for power, would open for the nobles to do the same...and don´t we have a blood cult in BT already(i may be mixing islands, so please correct me if I´m wrong)
I like the idea of creating religions but, like Tom said, we should avoid too many similarities with the existing religions...
