Yeah. Shandalar could work. You spoke with me, so that's fine.
Well, the official blurb is this: "Planeswalkers can be born at random in any sentient race, with no outward signs of their latent power. However, there is an incredibly remote chance that any given sentient, natural being will be born with a planeswalker's spark. When that being is put through a period of extreme stress—in many cases death—the spark can trigger, causing the individual to ascend and become a planeswalker."
Since on their own, each Sliver isn't exactly "sentient", their entire hive collectively could be considered a sentient being. And with slivers evolving so rapidly, it's certainly possible that one evolved technical "sentience" without exactly realizing it. And when the event occurred for your character(s) it latched onto that sentience and allowed the bits and pieces of a spark to converge and make him/her/them a Planeswalker.
As for how...well...like the blurb says. Extreme stress and possible death. This isn't exactly a normal circumstance, so you can be creative with it.
