You can get to a lineage tree page by either clicking the "view lineage tree" link on the factions page, or you can simply click on the
icon next to your clan / bloodline name on a character sheet.Trees are generated dynamically, so any new childer will show on there immediately.
Here's an example clan page.
Here's an example bloodline page.
Please note that it's a little rough around the edges when it comes to the blank space to the right of some of the bloodlines. And yeah, the smaller bloodlines will be off center, and the page doesn't auto-scroll to the family head yet. We'll be able to improve this over time.
