okay what it seems is
every day (for 12 days) there will be a new quest, perhaps for a reward.. this is the x-mas Safari! you can find the npc lady near the giant white dog in borealis, there might be others in other cities, i don't know.
also, returning are the quests involving the leets standing near Christmas trees. talk to them and they'll send you on a sometimes harrowing search for items they want. if they ask for a treatment laboratory.. just hand them one laboratory. you can split items by holding down CTRL, right-click on the item and hold, then pull the mouse up or down to adjust the amount.
finally yes, at tower sites there's anteleets with moose horns that give out all types of past and present Christmas gear (but not ALL past gear) and ice leets that drop strange ice machines which unfortunately turned out
not to be doomsday devices that would allow me to plunge RK into a frigid, icy plague. i won't tell you what they actually do, but to make them work you have to collect 8 different snowflakes which drop from the iceleets, then load the snowflakes into the machine
have a good holiday.. "good golf.. good tennis or whatever makes you happy"
