Membership of the True Elysians isn't particularly formal - hang around with us, make the right noises, and prove you'll have our backs in a fight, and you're more or less in. There are social gatherings of members organised on a semi-regular basis, which mostly consist of 'rec room, such-and-such a time', and cold-shouldering anyone else who tries to use the room, which are the main point of contact for most members of the group, as well as a good way to trade more or less discreetly in gossip, drugs, or anything else you want to pass around.
Those who form more of an inner circle do tend to have more private meetings, to which those who've built up sufficient trust will be invited.
