Lorwyn is set in a more traditional fantasy world, inspired by
Welsh folklore. The plane is a pastoral world inhabited by several major races: boggarts (goblins), faeries, elves, giants, treefolk, merfolk, elementals (including the flamekin) and kithkin. Five theme decks have been released as part of the set, one more than the standard four-per-expansion, which had been a long-time trend. The preconstructed theme decks are: "Kithkin Militia" (White), "Merrow Riverways" (White/Blue), "Boggarts' Feast" (Black/Red), "Elvish Predation" (Black/Green), and "Elementals' Path" (White/Blue/Black/Red/Green).
Morningtide As revealed in an advertisement in the trade publication ICv2 and later confirmed by
Mark Rosewater in his column,
Morningtide expanded upon
Lorwyn’s flavor and theme by focusing on at least five classes (Soldiers, Shamans, Wizards, Warriors, and Rogues) as well as a few minor class-based tribes (Druids, Archers, Knights, Clerics, and Assassins) in addition to the eight races of Lorwyn (Kithkin, Merfolk, Faeries, Elementals [Flamekin and Greater], Goblins, Giants, Treefolk, and Elves). Additionally, the three new mechanics keywords
Prowl,
Reinforce, and
Kinship were introduced in this expansion. Four preconstructed theme decks were released as part of the set. The theme decks are "Battalion" (White/Blue), "Going Rogue" (Blue/Black), "Shamanism" (White/Black/Green), and "Warrior's Code" (Red/Green).
Tribal The block has a tribal theme, now referred to in game as kindred, which focuses heavily on creature subtypes. The tribes of Lorwyn are composed of eight primary creature types. Each of these are represented by a primary color, as well as one or two others: ==Mechanics==
