Two of the Logrusfoils, Thought and Memory, obtained by unknown means, were wielded by Annadil during the duration of the Annadil Crisis and used to open the Gate of Revolution beneath the Air Pattern of Tir'Na-Nog on the Second Day of Darkness along with the Patternblades Greyswandir and Werewindle. After the Gate was closed, the two Logrusfoils were claimed by the Amberite forces before they could disappear into Shadow. It is believed that there were 13 Logrusfoils forged in total for Annadil's children, but who wields the remaining blades are unknown.
At the time of Unicorn no Seishi, the deposition of the known Logrusfoils are as follows:
- Courage?, wielded by "the smiling slayer." The Logrusfoil of House Suroth.
- Cunning?, the Logrusfoil of House Tremere. Whereabouts unknown.
- Determination?, the ancestral Logrusfoil of House Aesir, formerly held by Loewen of Helgram, given into the keeping of Motoko by him, then returned by her to Lord Odin.
- Fear?, hidden by "the Hanged Man." The Logrusfoil of House Formorian.
- Hope?, the Logrusfoil of House Danaani. Whereabouts unknown.
- Insight?, the Logrusfoil of House Darios. Claimed by Loewen of Helgram from the False Loewen he defeated during the climactic skyship battle. His intentions for it are believe to involve... well, keeping it for himself.
- Leadership?, the Logrusfoil of House Hendrake. Held by House Hendrake, normally wielded by Gilva of Hendrake.
- Love?, the Logrusfoil of House Olympus. Held by them after it reappeared on the throne forty years ago, after being long lost.
- Memory, the Logrusfoil of House Alars. Claimed by Shaft, and then stolen by the False Loewen upon Shaft's death. Claimed, like Insight, by the true Loewen, soon to be returned to House Alars.
- Peace?, the Logrusfoil of House Jesby. Held by Jesby after reappearing under the same circumstances as Love did for Olympus.
- Thought, claimed by Shizumaru, used by Moriya, now returned by Moriya of his own free will to Lord Nurgal (as it originally belonged to House Nurgal).
- Trust?, the Logrusfoil of House Vanir. Placed in a deathtrap by Annadil long ago, it was recovered at the cost of Moriya's life. It is now born by Mitsune.
- Vengeance?, the ancestral Logrusfoil of House Helgram, held by Lord Loewen.
