Buddy alternative to Ceremony of Eternal Bonding
Currently the only way to be able to travel to a fellow player is to marry them (rings). It is also one of the methods of obtaining a 2-seat mount.
Some cultures, religions, and real life situations make marrying someone, even in a game, not an option.
I suggest a buddy alternative in which you can only choose 1 buddy (cannot be changed for at least 3 months) where you can have the teleportation benefits (a ring, or, as a buddy, a bracelet) and a 2-seat mount. This would give players who have reasons not to marry still have the chance to play side by side with benefits otherwise not available.
