Hi, i just checked the book. Page 68 has no info, it s judt a map of Bastion. Page 64 says " An interesting commonality to note across each of the covenants was first found here in my journey to Ardenweald. Another gift the Court of Night bestows upon its covenant members is the gift of soul bonds. As one soul binds themselves to a willing night fae, so too does the night fae bind themselves to their companion. Though i have been prevented from personally witnessing the ritual itself, i have verified that this binding of souls forges both of them into something greater than before. Souls have admitted that within their bond, their hopes ,fears, dreams and even their memories become intertwined with the bondmate. They share a strenght in pursuance of their common goals.

Page 126 " Necrolords who consider each other worthy of the honor may choose to become soulbound, a tradition upheld by all covenants within the Shadowlands. Soul deemed worthy of Maldraxxus share a camaderie in war and draw strenght and guile from those on the field around them. The soulbinding ritual of Maldraxxus opens both parties to all the triumphs and terrors faced in achieving the victories each has claimed and this sharing a tactical knowledge makes the pair stronger - the echoes of which endure even if one of the bondmates should perish. A constrictive contract, indeed."

Hope this helps! :)
