- Raising the young:
In normal times, teams raise enough youth to meeting demographic replacement needs. Green teams will naturally have more availability for this than fascinated/obsessed teams, of course. Young kobolds are expected to hang around their parent team until they reach adulthood. At the end of the cyclical assembly, after doing their stint as governing body, young adult kobolds leave their team to join a new one in a pairing ritual, which ensure diversity. This also ensure fascinated/obsessed teams get a bit of new blood to take care of the older and more focused kobolds. Kobold growth cycles are fairly short and growing kobolds can contribute to background tasks so this isn't a huge imposition on teams.
Things are necessarily a bit different if the tribe seeks to increase its number of teams. When the assembly feel the need for this and consider resources are plentiful enough for it, teams will dedicate themselves full time to the care of a new group of youth brought in from all the other teams, which will form a fully fledged green team when they reach adulthood together.
- Team Care
While teams can broadly be assessed to be fascinated or obsessed, they still have a fraction of less focused kobolds thanks to the demographic renewal, as well as kids who participate in domestic tasks. This provide enough koboldpower for daily tasks, while other teams provide the material resources to see to the needs of teams on a mission taking them away from collection of necessities like food. This participation also has the side effect of kids learning care tasks as they grow and taking that training into their new team, where the young adults can in turn teach the next generation as they assist older members.
- Team Fascination
Fascinated teams naturally gravitate to the same subject, in an almost contagious manner, though that could also just be a factor of fascinated kobolds in a team pulling in as of yet unfocused ones into their projects, which only give one target for their passion. Fascinated kobolds aren't just focused on their work, they're also passionate about taking it up when they're brought to interact with others.
- Diet and cuisine
Kobolds are of course omnivorous. Their metabolisms aren't very good at storing up energy and they're generally not very happy on a diet of starches. As they live underground and were always designed to do so, they've never had to adapt to seasonal variation in diet. They favour animal proteins as their meal base along with fruits for quick acting sugars, veggies or mushrooms to complete nutrient needs and a smattering of seeds or roots to complete it. Kobolds also eat insects as a supplementary protein source.
Common travel food the tribe uses widely when on missions would be an assortment of dried meats, fruits, insects and seeds. When moving in bigger groups with a cook, teams rely on a stew of dried ingredients heated and rehydrated. If times are lean, foraged starches will be thrown in the stew with fruits and meats merely seasoning it. Feast food is a departure from the mixed together ingredients of daily fare, taking advantage of freshness to offer a palette of roasted meats and raw fruits.
- Fighting
The main kobold weapons are the spears and javelins. Kobolds are flimsy and like to keep at least a little distance when fighting if possible. With your tribe having access to magic, the core tactic in any larger engagement is to harry the enemy in a fighting retreat while the mages prepare something big enough to scatter them, then turn around and pursue their divided elements. If the tribe itself isn't at stake, kobold scouts will generally disengage before the enemy gets too close and set traps to deter following them towards the main body.
- Property
Who's that, never heard of her. Kobolds have practically no concept of private property. Teams will have their own stores of tools and resources as well as shelter they can assemble, while individuals retain a few trinkets. Fascinated kobolds also often borrow favoured tools for themselves and cling to them through their lives. There's no real concept of individual lineage, but kobolds care strongly about team lineage, with all adult kobolds honoring their birth team. When a young kobold mature and join their new team, they receive trinkets from the team that raised them as keepsakes. As they age, they'll gather a small collection of new trinkets from friends, admirers, partners or even their whole team as distinction for their work. Teams similarly receive prestige items from the whole tribe to honor their contribution and carefully curate those among them, exhibiting them during feasts.
- Other tribes
You know there are other kobolds around, mostly in the underdark but also in surface caves and burrows. A lot of them are in small team sized groups, without the more elaborate structures of the tribe. Others have retained larger organization, but they're further away from the land you roamed in the past. You haven't absorbed all teams you met because of the limitations your nomadic lifestyle put on supplies, but now that you're settled, it's possible you could convince them to join if you can show your ability to provide for them. Kobolds have a natural tendency to network across teams which has been kept down by their dispersion, so cultural factors will incentivize others to come together once they realize the resources for it are available. Your tribe is currently roughly the size a young adult dragon would have attending to them, leaving a lot of room to grow back to the population an elder one would have had as a following.
