Hob
The Hob Condition

Among the Virborne, Goblins were the least willing to endure the pain of sunlight. While Orcs embraced it as a trial of strength and Trolls sheltered in simple dens and shallow caves, Goblins delved deep underground. There they discovered the rare crimson Hob fungus, which grows only in deep, stale caverns and quickly dies when exposed to fresh air. Poisonous to most other races, an enhancer for the virborne.
The Hob condition is a long-term symbiosis between the Virborne's native fungal biology and the hob fungus. The fungus drives the existing symbiote into a heightened state of activity, dramatically increasing strength, endurance, recovery, and mental focus. The outer fungal layer thickens and becomes more vibrant, gradually shifting into deep crimson and ruddy hues while the body grows broader and more muscular. Horns, claws, and teeth darken, and the eyes often take on fiery amber or red coloration. These changes are unmistakable signs of an active Hob state.
The condition is expensive to maintain. Hob individuals require significantly more food, and regular consumption of the fungus is essential to sustain the enhanced symbiosis. Without continued doses, the secondary fungus slowly dies away and the body gradually returns to its natural state over the course of months or years.
The enhancement is not without consequence. The accelerated metabolism places chronic strain on the body's organs and slowly shortens the individual's lifespan. Hob cultures have developed specialized diets, medicines, and fungal remedies that greatly reduce these effects, but never eliminate them entirely. Just as significant are the psychological changes. Hob Virborne become more intense, competitive, and emotionally volatile. Confidence often borders on arrogance, determination becomes obsession, and anger is more easily provoked. Many outside Virborne cultures view Hob as an unnecessary indulgence, remarking that it makes an already dangerous warrior stronger while also making them less pleasant to live with. Maintaining a Hob population is above all else expensive not without tradeoffs and most goblin societies stop at ensuring the hob remains available for nobility, veteran warriors, and other individuals of exceptional importance.
Goblins are the undisputed masters of Hob because they cultivate the fungus and, being small, require relatively little to maintain the condition. Entire Hobgoblin civilizations can exist because their fungal agriculture can support them.
Orcs value Hob but do not depend on it. Their culture prizes enduring hardship as the true measure of strength. Hob is seen as an effective force multiplier for proven warriors, not a substitute for discipline.
Trolls almost never maintain the Hob condition. Their immense size makes it prohibitively expensive, and the metabolic strain is severe. A Hob Troll is a legendary individual representing an enormous resource strain to sustain them.
Paeleva (Half-orcs) are completely unaffected. The Hob cannot establish itself. To them it is simply another cave fungus—neither beneficial nor poisonous— similar to their relationship with the sun, which the Virborne often regard as one of the Paeleva's strangest and most enviable traits.
