The plane of Taramir has reached the end of its time. The struggles of the Waning Age have been forgotten, for the sun has set for the final time, leaving the world in darkness. Humanity survives in the vastness of the Grand Fortress, a stronghold that holds the last millions of the human race, and in the townships scattered throughout the darkness, perched upon a razor's edge. While humans are associated with all colors of mana, they are most strongly tied to white mana, and the works of their civilization unfold only as far as the light they can produce.
☼Taramir Block☼
Taramir Block consists of three sets: Taramir, Waning Light, and finally Age of Darkness. All three sets feature the new mechanics Salvage and Decay as well as the returning mechanic Cumulative Upkeep. In addition, Waning Light brought Fateseal into the picture. To this, Age of Darkness adds the return of Vanishing.
Salvage: Salvage is an activated ability that can be activated only when the card with salvage is in its owner's graveyard, when he or she could cast a sorcery. Salvaging a card exiles it and has the listed effects. Taramir introduced Salvage while Waning Light added off-color salvage costs and Salvage spells with effects dissimilar to their initial effect from being cast. Age of Darkness introduces Colorless and Nonmana salvage costs.
Decay: Decay is an ability word that causes one or more depletion counters to be added to the permanent with Decay, and causes it to be sacrificed when too many depletion counters have been accumulated.
~White Common Creatures~
Wall Tribal is a thing in age of darkness, an it's a thing centered in White. While every color has a few Walls, White has them heavily and throughout the rarities. Wall of Hope, Wall of Tattered Banners, and Signal Tower are a pretty heavy mess of defender, and the nonwall creatures all have quite defensive stats

~White Common Noncreatures~
Exaltation is part of a cycle of vanishing auras. It's probably the least offensively-minded of the lot, and it (naturally) has the shortest vanish timer, hanging around only until your next upkeep. Beyond that, White has some pretty standard removal spells with 4-mana effects that exile an attacking or blocking creature, or anything with a downside. The latter effect would be uncommon at one mana instant but I felt it a safe common at 4 sorcery. Interestingly, every white spell results in a creature leaving the battlefield: the two removal spells, of course, and all the others will eat one of yours (probably)
