So the Compass doesn't appear in Fate/strange fake which is what Fake/states night eventually became?

Right, it doesn't show up in Fate/strange fake itself (though that could change with the new novels coming out starting next month).

<p>Shirou could feel the presence of Medusa/Rider in the 5th Episode of Unlimited Blade Works.</p>
<p>I would say, if a third rate novice Magus could feel the presence of a Servant, a Genius like Rin wouldn't need her Mana-Compass anymore during the 5th Grail War.</p>
<p>Also, if I remember correctly. Command Seals vaguely &quot;ping&quot; Servants or strong Mysteries? Rin's Seals react in the Fuyuki Park in Episode 0 of UBW and she later feels the presence of Riders Blood Fort Andromeda, also during Episode 0.</p>

<p>In Fate/Zero, Rin is given a Mana Compass by her father which she uses in her search for Kotone. I've only seen up to episode 10 but I know she'll appear in a later episode where she will receive the Jewel Pendant which becomes the catalyst to summon Archer in the 5th war and saves Shirou's life.</p>

<p>However I don't remember her Mana Compass being mentioned in Fate/Stay Night, nor can i foresee a situation in Fate/Zero where it would be destroyed. Given how it works it seems to be quite a useful tool Rin could've employed in the 5th war.</p>

<p>So I am wondering, is it stated what happens to the compass, since it seems Rin treasures the Jewel Pendant she was given, since it came from her father, and I would assume she would treasure the compass as well.</p>

What happened to Rin's Mana Compass?

Also, if I remember correctly. Command Seals vaguely "ping" Servants or strong Mysteries? Rin's Seals react in the Fuyuki Park in Episode 0 of UBW and she later feels the presence of Riders Blood Fort Andromeda, also during Episode 0.
