Urza was born 0 AR, and the raid on Serra's Realm (according to the Wiki) was in 2,500 AR. It did not happen later.Quote from zekingfx »Sorry but i have a question about the mtg lore timeline. According to the mtg wiki's timeline, the raid on Serra's plane happened way way way before Urza was even born. Did Urza travel through a rift with the weatherlight or does can planeswalkers planeswalk between time?
For storytelling purposes, most planes operate on similar time, but there are shenanigans out there. I'm sure there could be a plane where time moves differently. Usually it's just the units of measure that are different (since not all planes orbit a sun at the same speed... or at all), but when someone says 'year' for all intents and purposes it's the same measure of time on most planes.Also do the multiverse run in a linear time or do each planes experience time at different speed? Is it possible for a walker to planeswalk from a plane for just a second but in actuality experience more than a second of events?
