The spreaders on a bal’kar a set of four tentacles located on the front of the bal’kar’s lower body. These long tentacles with their mouth-shaped cups are capable of spewing out long strands of weavers used to construct the various hive structures of the bal’kar.
The bal’kar’s four black spreader tentacles are located on its lower body, near their front. At their base, these tentacles are generally very thick and taper outwards ending in a mouth-shaped cup at the tip. Within these ‘mouth cups’ are a series of extremely long prismatic green proboscisesProboscises (pro·bos·cis·es) Elongated tubular appendages, typically used for feeding or sucking. that are linked to the bal’kar’s own internal seethers. The ‘mouth cups’ are able to produce an almost endless string of specialized seethers, called weavers, that can extend for kilometres at a time.
Each individual strand of a weaver is capable of branching into a new weaver. That new weaver can, in turn, branch into additional weavers and so on. The bal’kar can intertwine these weavers together to build hive structures and nests (See Hive Structure). When a bal’kar is building structures or growing their weavers, the weavers and spreaders are at their most chaotic, often on bigger projects completely disfiguring the bal’kar’s anatomy. This can often make a bal’kar who is growing a hive to be almost unrecognizable as if the Bal'Kar himself has become part of the fleshy structure it wants to create.
The spreaders of a bal’kar serve two main functions. First, the spreaders are able to extrude seethers into a form of sticky web-like substance known as weavers, which the bal’kar form into stuctures to better serve the hive. Secondly, a bal’kar can use their spreaders to assist in movement, working in conjunction with the thrusters to propel the bal’kar forward.
Hive CreationrhynchocoelRhynchocoel (rhyn·cho·coel) A tubular cavity that holds the introverted proboscis. when inactive. When the muscle wall of the rhynchocoel contracts, seether tentacles are forced into the rhynchocoel before being expelled as weavers. Once expelled, these sticky, branched weavers spew out from the mouth cups, splitting into a net that spreads upwards and outwards around everything in its path; quickly changing from a bright green color to black.
The weavers continue to spread outward eventually detaching as they separating from the spreaders and the bal’kar. These separated weavers remain alive and continue to function as semi-autonomous organism; weaving and growing following the will the bal’kar to form hive structures and other biological constructs.
Depending on the amount of weavers used, it can then take a bal’kar anywhere to several seconds to a few minutes to ready their spreaders again. Weaving layer upon layer of biological mass the bal’kar’s spreaders create living structure after living structure all in the effort to grow the hive. In turn this growth helps further the will of the bal’kar; the bal’kar forming nests and hive clusters to cater to the bal’kar’s way of living. Before long, towns, cities and entire landscapes are covered; transforming the ecosystem to suit the bal’kar. Over time, bal’kar build new hive structures above the previous, crafting vast living tunnels connecting the various layers of hive.
As bal’kar become the dominant form of life upon a planet, they spread unchecked across the planets surface; creating layer upon layer of hive, reshaping the planet to their will. Over time, the planet loses its shape and the bal’kar begin to form a bal’kar globule upon the planet.

Along with the thursters, the spreaders are used as the bal’kar’s front legs; Pulling the bal’kar forward when in a less amorphous and mobile state.
Spreader tentacles can be used recreationally to enhance the pleasure inside of a bal’kar’s body. Externally this can be accomplished in many ways from grasping at the breeder, to shooting thick strands of weavers up the urethra or abdomen. Internally, the spreaders can spew their sticky weavers deep into another bal’kar’s body, penetrating deep into them stimulating the nervous system in many different ways and massaging the bal’kar’s internal organs. Alternatively, the spreaders can force the weavers into the skin of another bal’kar, infesting their body as the weavers grow and spread underneath the bal’kar’s skin; literally forming hive structures from their body. It is important to note that when used in the last way, the effect is not permanent. Instead when the bal’kar wishes it they simply free themselves by wiggling and writhing their seethers free from the hive structure.
