To my knowledge, there are only three ways to travel through time in the classic WoD:
- Forward at a rate of one second per second as anything else. That's nothing special, as that is what all the universe does.
- Special relativity applies, so you could slower in with \$\frac {1\text{ s}}{\gamma\text{ s}}<1\frac{\text{s}}{\text{s}}\$ in relation to the non-moving world, if you travel fast enough by mundane means, as \$\gamma={\sqrt{1-{\frac{v²}{c²}}}}\$ with \$v\$ your speed and \$c\$ the speed of light in a vacuum. Those speeds need a lot of energy, very long acceleration or Magic - and are far beyond what Swara or vamps with celerity 10 can muster. But (thanks to the Technocracy) relativity applies. Ok, enough physics.
- Use of the Time sphere as a real Mage (and getting clobbered by Paradox in the process).
- And of course use of an artifact that uses time
- Use of the Temporis Disciplin as an ancient Brujah.
Within some broad borders, there are two ways for Fera and other shifters to experience past times:
- Visiting an umbral realm, most notably a Wolfhome or the Battleground, allows to experience a past time that gone by, but you don't actually travel back in time.
- This also is open to Spirit mages even.
- Using Mnesis, a Mokolé can experience and relive the past, though again it is more experiencing it not changing it by being there.
There is one fringe case that could be seen as time manipulation:
- Level 5 Nomenclature as a Mummy allows to erase somebody from history. They never have existed after you used the rite. Only you remember them.
