You were stationed in Chaos Nexus a Fortified outpost in the Freaks Fortress world/Elements of Insanity universe within a transformation room you are given options to change yourself into before going out to the EOI world as a field agent

You'd see a computer screen light up giving you three options on what to choose before going out to the EOI world

[Directive: User, please select from the transformation options displayed below.]

[Choice 1: EOI Pony Form - Assimilate into the ranks of the twisted and chaotic EOI ponies, integrating into their society to access their information networks and inner workings.]

[Optional within Choice 1: Opt to be a 'custom OC' pony, endeavoring to survive within the EOI landscape.]

[Choice 2: EOI Human Form - Adopt the guise of a human from the EOI universe, traversing the perilous terrain and engaging with human settlements to collect intelligence and forge alliances.]

[Optional within Choice 2: Choose to be an ordinary human striving to survive the EOI Landscape.]

[Choice 3: Freak's Fortress Creature - Undergo transformation into a monstrous and powerful being from the Freak's Fortress World, enabling deep infiltration and reconnaissance of this daunting fortress and its environs, with the possibility of discovering crucial secrets and weaknesses.]

[Upon making your choice, you will be teleported to the graveyard where the 'Element of Insanity' tale began. From that point forward, your actions are your own, but refrain from disclosing any details about 'The Shadowstorm' operations here.]
