In the summer of 2015, the Delta-Storm happened, an event where tens of thousands of crystals rained from the sky and landed on the earth. These weren't ordinary crystals (Named Delta-Crystals), however, as they radiated with strange otherworldly energy (Nicknamed Delta-Point Energy) that granted strange abilities to those who were exposed to it. These can range from teleportation to super-strength to manipulating the elements and even replicating the powers of others; the possibilities are endless. These superhuman entities are called Deltahumans (The older term was Metahumans, and sometimes they are referred to as Deltas/Metas). There are five different types of crystal/delta-point energy (Red, Blue, Yellow, Green, and White), each granting another ability. Still, there's also the chance that someone may get two different types of energy (Known as being Chromatic, which is rare). However, powers are completely random within those categories, and someone can get a completely useless power. Only a select few are compatible with the energy (stated to be about 15% of all humanity). Still, once they are exposed (from the crystals or contact with other Deltahumans), it'll rapidly spread to the rest of their body.

This is known as an Exposure-Event. Once exposed, a person either develops their abilities Naturally (over time, ability will manifest) or Under-High-Stress (in high-stress situations, ability develops faster). The energy within a Deltahuman is invisible to all except special equipment. When they use their power on the environment, they project a bit of it (only to fade away once they've ended their ability). Every person's ability is different and unique to them. However, some powers are Hereditary. These are few and in between but are more likely to occur if the mother is a Deltahuman and Deltahuman children usually take after the mother power-wise. There's an enormously high chance if the parent was compatible with the energy, the child would also be consistent with the energy.

Deltahumans are naturally drawn to one another through the Black-Fall Effect. It's a subconscious draw to one another that's so subtle that nobody can notice - but even the shyest introvert will be drawn to other Deltahumans. If a Deltahuman touches a Delta-Crystal, they'll receive a massive power boost if the crystal corresponds with their type. For example, a Red Deltahuman will get boosted from a red crystal, but it'll only be slight if they touch a yellow. However, there are a few drawbacks, as powers are linked to the body and mind, and overuse can result in exhaustion and physical pain. A Deltahuman pushing themselves too far will result in Ashing, which is best described as the body self-destructing. They'll fade into ash, and the survival rate is also meager - around 4%. There's also another side effect that makes it risky for Deltahumans to use Delta-Crystals.

A new nefarious chemical has developed in recent years - Power Serums. A mysterious organization known as REAPER is the prime distributor of these serums; these glowing vials of liquid can grant various powers once consumed. They can usually be bought by shady means. However, the REAPER organization sometimes distributes them for free for purposes unknown (either to drum up chaos or test out a new serum). While Deltahumans are a recent development out in the world, some suspect that Deltahumans could have appeared far earlier. It's only a suspicion, right?
