Magran
From Tardis Wiki, the free Doctor Who reference
Magran was a scientist on the Vault of Stellar Curios. The presence of a time echo of him, was part of proof there was time leakage. He was shown by the Fifth Doctor a way to stop the time leakage by having an inverted light cone showed hyperbolic orthogonality, and he wondered how that would help Kalinda's project.
