Guardian Tree

Description
This tiny sapling might not look like much, but if you plant it near a House Seal and take care of it, it might repay the favor some day. -- Directly from patch notes

Growing time
According to calculations, growing the tree to 100 % will take between 11 to 12 real days for the first stage. After the first stage you have an option to evolve the tree. Once you evolve the tree it explodes into growth doubling the size. Your grow timer starts again leaving another 11 to 12 day before reaching 100%.

Once Fully grown this tree provides (within zone) each family member with increased life regeneration, slight speed boost and over 9000 light shards but they can only be spent on the tree nyph for a good time. o.O
