The Very Logical Prize Puzzle # 207

[Matakari]

Generally, I get this one pretty quickly, but having some problems here! Some help will be appeciated with the following, please!
ACROSS;
10. Marten is poetically dark ( 5 ): ????A
11. Involves internal parts, absent a little river( 7 ):
??T???T
28. A narrow pass for Nick ( 5 ):????H

DOWN:
1. Objectionable behaviour has magnificent connotation but with fatal three points I included (5,6,4):
?E?????D?A?A???
14. Sometimes included at 7 down, but probably not by Limbaugh ( 10 ): ??S?G?S???
5. Bursting forth heartlessly, meant pure chaos( 8 ):
E???????
6. Voluntary forbearance creatively can be set in 7 down's bailiwick (10): ?????T???E
7. 13 across, for instance, is delightful with half a dozen. Oddly true, to a point! ( 8,7):????N???I?T?E? ( CARDINAL VIRTUES?)
Many thanks for your help!

7d Your ?s & letters don't quite add up! But what is the answer to 13a, on which 7d appears to hang? Could it be heavenly virtues?

28a notch?

[kettledrum]

10a sable
1d seven deadly sins ?
5d erumpent ... anag 'me(a)nt pure'

[millder]

5D erumpent

[johnalex]

6d Abstinence . . . . anag: can be set in

[kettledrum]

11a entails? ab SENT A LI ttle ... anag?
14d. bit of a shot in the dark here, but assuming this Xword is based on sins & virtues ..... liberality

[Matakari]

Thanks for the help, kettledrum, millder and johnalex! I found the seven deadly sins, abstinence and entails, and with your assistance, the puzzle is working out very nicely! Thanks again!

Generally "I" get this one pretty quickly.......(yes,day1)

You wanted help with as many answers for this crossword last month!!!! ;-)

[Matakari]

For your information, MLN:RUGBY, I have been doing this crossword for a few years now and this is only the second time that I have asked for help! Hence the: "I" generally get this one pretty quickly bit. And if I am not mistaken, last month I asked for help with ONLY 4 clues. So, it might be better for you to keep your trap shut if you have nothing positive to offer, old man!

[MLN:RUGBY]

Old man's trap now open again with something "positive" to offer!
I'm "positive" we'll see you asking for multiple answers to various crosswords again (and again) this week! ;-)
