If we’re talking locations?
A good chunk of the Kaldorei plant the reborn World Tree on the stump of Teldrassil and watch as the tree starts to grow with sudden vigor, slowly spreading vines and roots across and into the charred stump as the moon overheads turns from black to a pure, brilliant white unseen anywhere else on Azeroth. The Kaldorei see this as a sign of Elune’s renewed attention and favour in their people, and celebrate as a new surge of Wisps, Ancients and Owlbears are seen across the land. The lack of Dryads and Keepers, however, is seen as an ill omen, and many Kaldorei fear that Malfurion choosing to stay in the Shadowlands has angered or offended their beloved Cenarius, and fear a growing divide between their former allies and their newly reborn kingdom.
A smaller portion are sick of it all, however, and move to Duskwood to settle around the Emerald Gate in the center of the region, stating they don’t believe Tyrande can, or will, protect them since she left them all to save Malfurion, and start a ‘Little Teldrassil’ all of their own. Unwilling to share borders with the Horde and refusing to move away from the strongest defenders within the Alliance, the Kaldorei of Little Teldrassil instead turn their Druidic mastery and keen hunting skills to use for the Acting Regent of Stormwind, doing much to help restore Westfall to some semblance of usefulness and driving Kobolds, Gnolls and Defias hold-outs either out of Alliance territory or into a shallow mass grave.
Tensions between the two camps are, to be blunt, coldly polite at best, despite overtures from Tyrande, Shandris and Jarod Shadowsong, with the two groups of Kaldorei remain stubbornly opposed to each other’s goals
The Ren’dorei move to the mostly-abandoned town of Darkshire and make it their new home, needing time and space away from the Light to truly come to terms with what has been done to them, and what they can do now to take full control of their new, altered natures. Some night or dark-themed Sin’dorei buildings to replace or add onto the dilapidated and out-dated structures of the village of Darkshire. While the locals are more than a little creeped out by their new neighbours, the stubborn and resilient Humans of Duskwood appreciate the lethal skill and honed talent of both the Kaldorei and Ren’dorei.
Gilneas gets rebuilt and turned into a new capital for the players to use.
Thunder Bluff gets expanded, with mining down into the mesas and additional bridges to create enough space for visiting Tauren and Tauren-kin, including the Taunka, the Highmountain and curiously, several Yaungol ‘ambassadors’.
The Quillboar menace is dealt with and the Tauren now have to deal with rogue Elementals, Grimtotem saboteurs and angry Kaldorei spirits who have come down from Stonetalon to avenge the destruction of the Druidic school there.
Undercity is rebuilt and with less slime, please.
Gnomeragon is scavenged for parts and Mechagon becomes a phased area where Gnomes, Mecha-Gnomes and those who are Exalted with at least one of these factions can go and treat is as a micro-capital, complete with bank, auctioneer, transmog, hairstylist and trade chat.
Orgrimmar, Azshara and Durotar having significant Druid and Shaman presence trying to cleanse the water supplies and encourage an alarming number of trees to grow since the Horde is barred from Ashenvale now and the Horde’s need for lumber, both for rebuildings their fleets and the cooking fires and smithies of the great city of Orgrimmar, and Azshara is the closest and easiest place for the Horde to secure lumber unmolested by angry and vengeful Kaldorei.
