Inconclusive The Custodians and the Sisters hold the daemons in the tunnels beneath the Palace; stalemate.

After Magnus’s breach, daemons poured out of the Webway beneath the Imperial Palace. The Emperor, chained to the Golden Throne, together with the Custodians and the Sisters of Silence, waged a hidden war in the endless tunnels near the “Impossible City” of Calastar. The Custodians were bled white — down by 90% — but held the breach, at the cost of the Emperor being unable to leave the Throne.
