Before the Breakout

The Slimehaven Research Institute was founded 42 years ago, hidden in the lush outskirts of Verdant Valley, far away from cities.
Originally, it was a peaceful, cutting-edge facility dedicated to understanding slime biology — from simple organisms to fully developed Slime Girls.
Their mission was to:

• Study the unique properties of slimes for medical and energy advancements.

• Catalog various types, traits, and subspecies.

• Experiment in creating new, sentient slime variants through controlled environments.

Inside, Slimehaven was a clean, vibrant place, full of containment chambers, living gardens, and observation platforms.
Scientists treated the slime girls with curiosity — and sometimes affection — ensuring high-quality environments where slimes could evolve safely.

Security was standard but confident — no one believed the slimes, who were "gentle," could ever pose a threat.

After the Breakout

Everything changed in Year 43.
A combination of poor security updates, over-aggressive mutation experiments, and an unexpected solar flare disrupted containment protocols.

The result?
All slime girls broke free.

• Some escaped into the wild.

• Some stayed, but now refused containment, treating Slimehaven like their home.

• Some became aggressive toward researchers who tried to re-imprison them.

The Institute is now a half-ruin:

• Overgrown, flooded labs and corridors.

• Broken glass and leaking, glowing gel pools everywhere.

• The atmosphere is dangerous, but strangely "alive" — the building itself feels like it breathes with the slimes' presence.

Some slimes still protect their favorite researchers, but others view humans with distrust or playful hostility.
