@Aria Aaaaaaaahm. Be cool? The game's only taking apps for roster PCs while staff is on a break until August. However, there are a ton of characters on the roster. If you pop on at some point and have particular types of PCs you like playing, people will generally be able to help point you at some suggestions on the roster.
If you app, ask about the @randomscene command, cause you'll have access to a two-week window where you can basically collect a nice amount of newbie bonus XP.
Probably one of the hugest strengths of the games is the depth and mystery of the lore and metaplot, and IMO it does benefit from not sharing OOCly the many secrets you'll come across ICly. (This was hard for me. I am used to games where literally every log gets posted.) Arx actively sets up its systems and structure so that you only have OOC access to things your character would have IC access to/knowledge of, so I think it works out better when you lean into that.
There are dangers on the game from both NPCs and PCs, but it looks like you've been around the WoD block, so you probably won't have the adjustment shock I did coming to realize some of the PVP elements. (That said: those elements are pretty carefully controlled. Players are not given leeway to go murder whoever they want just cause. I say that as someone who's been pretty critical of some of the PVP structural setup and advertising both on this forum and to staff directly.)
Whatever character you pick up will have family and/or org connections, so utilize those! There's a pretty strong welcoming vibe on the game, helping to acclimate new folks instead of giving them a hard time for getting a title wrong or something. There is an Info channel that I lurk in wait on that is great for asking questions after you have an approved PC.
Okay! Those are some things I feel like I'd want to know coming in. Speaking with the experience of having at one point done the opposite of some of them and redirected.
