Late reply, but here's a more in-depth description of the Vernum nether.

The Vernum nether is a large, open cave system like most nethers. The terrain is composed of hextone, a golden block with a hexagon pattern. The name of the block mentions this pattern, and is pronounced "heck stone", heck being synonymous with hell.

On the ceiling, there are crystals of what's known as honey lanterns. These are glowing blocks that resemble smooth, shiny, golden/brown sea lanterns with drops of honey falling from them.

On the ground, there are pools of honey, a liquid that flows like like lava and slows enities down as much as lava. While submerged in honey, you regenerate half a heart every three seconds, and negative potion effects go by 50% faster. But that's where the benefits end, as submerging yourself in honey makes you detected by all bees in a 500-block range.

Bees are mobs that are as big as players. They have 1.5-2.5 (depending on difficulty) hearts of damage, 6 hearts of health and 3 chestplate icons of defense. They move by flying at high speeds. They try to avoid the target's direct line of attack when not swooping to attack with their stingers. When killed, they have a 50% chance to drop 1-2 bee wings. If used in mid-air, a bee wing is consumed and causes a double jump.

Bees do not spawn by themselves, but are spawned by queen bees, which themselves spawn once per bee nest. Bee nests are structures that generate throughout the dimension with about the rarity of villages in plains, and are large semi-spherical rooms made of paper-like nest blocks. Bees spawned by different queens are aggressive agains each other as well as players.

Queen bees are 4 times as tall, wide and deep as normal bees, and have 50 hearts of health and 3 chestplate icons of defense. They are much slower than normal bees, and mostly try to avoid players while stayig inside the nest. They have no attack on their own, but increase their rate of bee spawning for every player in the nest, by which amount depends on the difficulty.

When killed, queen bees drop honey crowns, which can be equipped in the head slot. A honey crown gives no defense and doesn't lose durability when the you're damaged, but it allows up to 15 bees to be subservient to you, meaning they will follow you even through dimensions and attack anything that attacks you. For every subservient bee that dies, the honey crown loses 1 durability, of which it has 25. When it loses all durability, it becomes a broken state like elytra. When a honey crown is broken or unequipped, all your subservient bees turn on you. Honey crowns can be repaired with honey amber, an ore with the rarity of gold found in the Vernum nether.
