There existed three families among the Floating Spiders, similar to the Aristocratic and Royal Families in Marble City. They were the Web Family, created by Rhachis Ancestor Web, the Warlord Family, created by Rhachis Ancestor Warlord, and the Puppet Family, created by Psychic Ancestor Puppet.
Having adopted many customs and practices from the humans, the three Families of the Floating Spiders conformed to the same, i.e. possessing an Unranked Skill per Family. They possessed three Unranked Skills in total, created by each Ancestor respectively.
The oldest and the most witnessed Unranked Skill among them was Web World. Only Developer and higher Tiered Floating Spiders were able to inherit this Unranked Skill, a Warrior-based Skill. Using the Unranked Skill, a Floating Spider was able to create a sphere of silk, with innumerous interlining pathways and patterns within, each of them possessing their own functions.
