Here is an idea for a utility, joinable by any background, but you
must be max level in 1 guild. Disciple, squire, and explorer would not
count. Guild name could be something like 'Command School' only 3
levels or so, but would be able to train Rescue and Leadership to
a max of about 50% or 60%. Something that will work sometimes, but
lower or equal to what most nomad guilds get it (except crimson ofc).
This would be handy for those 'backrow leaders', and force players
to spend levels in a guild rather than just say give mage/tarm/etc
those particular skills. Just a thought
