Discord allows for custom emoji, and we have definitely taken advantage of that feature. Some are related to Nerdfighteria inside jokes, some to Tuataria inside jokes. (Hopefully useful) explanations are given below. A list of previous emoji is also at the bottom (because Discord has a limit of 50 emoji per server).
