And remember if you go with a mute character, remember that a) mute does not equal unable to communicate AND it also doesn't equal "no one else will ever find out my character's secrets," in the world of Armageddon. b) Barrier is not impenetrable, and will wear off over time, so don't assume that your character simply has their barrier up 24/7, AND don't assume that other -characters- of the world will believe your character if your character is somehow able to convey that their barrier is up 24/7.
Or, you could ignore all of what is said (please don't), and role-play exactly that. That your character is able to maintain a 24/7 barrier around their mind that is impregnable. Other characters in the game will quickly realize this is not true when they chance to use their own mind abilities to contact your character during the time period when the coded forces your barrier to drop because it's been up too long (strain on the brain). You will be known as that lunatic that thinks they've got uncommon mind abilities that just aren't there.
Or, let's say for whatever reason, the code rolls in your favor and your low-powered barrier manages to keep the average person out of your mind. This is not a common ability available to the general population in Zalanthas. There is a type of individual who does have the power to do something like that, though. They're called various things on Zalanthas, such as "Mindbender" "Mindworm" "Freak" "Witch/Mindwitch" "Abomination," and other flattering terms. The mere possession of uncommon psionic abilities is an offense punishable by death in most of the Known World. You do not get a trial, there are no lawyers or open sympathizers to speak up on your character's behalf. They are a freak of nature, a monster, and you will have the common man more than happy to turn you in and see you die.
You might get an awesome death scene. You might not. In the end, the character you poured your interest in to will have lived for two, three hours (an average of time spread out over however long) and then they are dead. Forever.
Go easy on yourself and make your first few characters two-bit cast members that are expected to show up, show off how cool someone else is
, and then die. You will have all too many experiences in the future of having your heart ripped out when a beloved character dies in the blink of an eye, without a "cool death," because you walked west, an aggressive mob came into the room, hit you before you could react, and you died.
Don't give Zalanthas any more of your heart up front than it will already take. Zalanthas hates you. It wants you to die so it can feed on your frustration and anger.
