From Wookieepedia:
Life Day was a Wookiee holiday celebrated by the inhabitants of Kashyyyk every three years. It was a celebration of the planet‘s diverse ecosystem and the many forms of life it encompassed. It also was a time to remember family members who had died, and the young ones who continued to bring new life to a family. Life Day was a sacred holiday, and many Wookiees considered it their duty to return to Kashyyyk in order to celebrate it. Life Day was held once every three local years for many generations, but during the Galactic Civil War, its importance to the Wookiees became more pronounced. Wookiees were spread across the galaxy, either because they had been enslaved by the Galactic Empire or for personal reasons, and they began celebrating Life Day each year as a way to remain in touch with their history. Over time, the holiday found its way into various other cultures. “Life day” was also used as a term to describe the anniversary of one’s birth.[2][3]
In Star Wars Galaxies, there were events from 2004-2011 that dealt with Life Day. Life Day-themed paintings were issued each year, with 2004 having the Life Day Kashyyyk, Matriarch, and Patriarch paintings; 2005 having the Memories Past, Pilgrimage, Triumph paintings; 2006 having the Gift giving Wookiees, Kashyyyk at night, Proud Wookiee, Red Robed Wookiee, and Wookiee with pups paintings; 2007 having the Ancient Life Day painting; 2008 having the Family Bonds painting; and 2009 having both a reissuing of Family Bonds and the issuing of the Life Day 2009 Painting.

By chance one day this week, I found myself on Vreni Island in Galaxies.
There, what to my wondering eyes should appear, but the Wookiee Life Day Quest giver I hadn’t seen in years. I’m not certain if some of the other holidays have been in the emu game and I missed them, or what, but, I love the paintings from this quest, and my second favorite character, my Wookiee Architect, loved loved loved the red robe from this quest. Wookiee wear in the game is notoriously colorless, but here a statement could be made.
The other big thing is, though this quest takes you to Endor (or alternately to Dathomir), a non-combat character could make it from the Endor Research Outpost to the Life Day waypoint without insta-death if they were careful and watched their radar like mad.
If you go:
Do the quest the same day you take it or the waypoint may disappear from your datapad.
It costs 8000cr round trip to go to Endor, but I feel your chances of success are greater than on Dathomir, which is 4000 round trip (from Coronet). All my memories of Dathomir say no lowbie can make it to a waypoint even a few meters outside the starport without being crushed.
I’ve sent two characters so far, getting the robe for my architect and the Wookiee Life Day Orb for my Ranger.
I MUST get some of the paintings! Somehow I will send my other characters on the quest.
There have also been a series of Grinch sightings on varying planets. Since he appeared briefly in Coronet, I sent Dustbunnie (occasional reporter for the Corellia Times) to get a picture of him without being killed, as she has zero combat skills. The Grinch is missing his Grinch outfit, yes.
She also spotted Santa slipping through the city.
