1st Gen Lintlings: Only one exists so far, that is Mother Lintling. The original lintling who created all living lintlings. She seemingly has no limitations and thanks to the powerful heart token in her chest she has boundless magic to use at her disposal. She can use Illegal - Common features as she pleases.
2nd Gen Lintlings: With 10 creation slots at their whim, these lintlings can create detailed and wonderfully crafted lintling companions and might even craft them lovely outfit to go with. 2nd Gen's have access to all Common, all Uncommon, and 1 Rare Feature.
3rd Gen Lintlings: Having only 3 slots to their whim they are normally a lot more cautious about using their precious life magic to create more lintlings. But in serious situations they won't hesitate to help make more if necessary. These little ones might also make a functional accessory for their lintlings to use once they are made. 3rd Gen's have access to all Common and 4 Uncommon Features.
4th Gen and Lower Lintlings: No creation slots. These little guys normally do not have the magic capacity to create new lintlings. Instead they bring supplies for the higher gen lintlings to create their new companions for them. These little ones only get access to Common features and 1 Uncommon feature.
