This token was originated in the wallet of a holder of the now-deprecated Tomb Series Index Marker V1, during the upgrade process for Index Marker V2. It recognises that the original holder had redeemed a V1 Index Marker prior to the migration to V2. The upgraded V2 Index Marker token can be seen here: https://opensea.io/assets/ethereum/0xa5c93e5d9eb8fb1b40228bb93fd40990913db523/929
