Large broods are commonplace, typically between 40 and 60 members per family. Driders that come of breeding age normally are pushed out of their brood for a year or two to meet other broods. Successful meetings help to bond different broods tighter for mutual defence and resource sharing. For most Spinarrans, mated pairs are a single drider picking an Arachne they really like and taking them as a mate. It’s is not very common for driders to pair together or for arachne to pair together. While most broods lean towards monogamy some broods do lean more towards maintaining relationships with multiple partners. On some occasions, a drider will take multiple males as a harem. The culture promotes good companionship between mated pairs and the addictive nature of the driders narcotic venom makes couples much harder to break apart. In times past, the death of a mated drider almost certainly meant the death of the drider’s mate, with the withdrawal from their addiction to the drider’s venom giving them a slow, aching death. These days, synthetic venom can be used to wean a grieving Arachne off their drider’s venom until they are ready to find another mate. Some family members could even donate their own venom to their grieving sibling, parent or offspring, though this can result in awkward situations or acts of incest due to the euphoric nature of the venom.
