Contacts

PCs can track relationships between themselves and NPCs.
PCs can track either Friendship, Rivalry, or Romance.

Friendship Thresholds
0: Associate
10: Friendship
20: Fellowship
30: Devotion

Rivalry Thresholds
0: Associate
10: Competition
20: Rivalry
30: Enmity

Romance Thresholds
0: Associate
10: Romantic Interest
20: Love
30: Soulmates

Any relationship starts at the level of associate.
When PCs make a friendly or hostile gesture, PCs may make a roll with a relevant focus.
This test should be based on the personality of the NPC in question, and should be plausible given the type of relation the PC wishes to pursue.
This test may be attempted once per day, and the Dragon Die determines how much the relationship increases.
When a threshold is reached, the relationship progresses to the next level.
When the relationship reaches an new level, the test begins again at 0.
Performing acts that an NPC disagrees with will likely reduce the relationship score.

When meeting an NPC, PCs may immediately start off on the romance path, if they like.
When a PC wants to change the relationship with the subject to a romance, they may make a roll with a relevant focus.
On a success, they may switch from friendship/rivalry to romance, while staying at the same level.

Contacts are NPCs which are friendly towards the PCs, but aren’t tracked.
PCs with the Novice degree get a +2 to their initial roll to make someone an associate.
PCs with the Journeyman degree may try to get favors from someone at associate level.
PCs with the Master degree may skip to the first threshold if they pass a COM (Persuasion) roll.

If this person responds well to honesty or kindness, then COM (Persuasion) would be a wise choice.
If this person happens to be confident sexually, they may appreciate COM (Seduction).
If this person is bookish and is impressed with knowledge or likes talking shop with scholars, then a CUN (Lore) test may be appropriate.
If this person likes poems, PCs could present them with a poem and a CUN (Writing) test, or a DEX (Calligraphy) test.
If they like talking magic, PCs make a Magic test with a relevant school focus.
If they like to be understood, try PER (Empathy). Maybe they also appreciate being inspired with WIL.

The most obvious choice of test for a rivalry would likely be STR (Intimidation).
Perhaps the person is a mage, and might be put off by WIL (Faith) tests.
Perhaps the NPC is protective of their things, and would be bothered by a DEX (Legerdemain) test.
If the person dislikes alcohol then a CON (Drinking) test would put them on the defensive.
If PCs really want to insult their intelligence (and possibly make some great banter) a COM (Animal Handling) test could be used.
COM (Performance) tests could be used for those NPC who like their peace and quiet.
Setting simple traps near their things with DEX (Traps) (nothing deadly, just things like snares or tripwires) could really annoy them.
If the NPC really doesn’t like having his problems analyzed, drag them out in the open with PER (Empathy).
